“Original people all over the world have harvested and enjoyed algae and sea weed for centuries. Spirulina, making a strong comeback at health food stores in the United States, is one such ingredient. It was once harvested off rocks at Texcoco lake by the Mexica, who called it tecuitlatl or cocolin – Nahuatl for “rock excrement” and “water viscosity,” respectively. It was then prepared into patties, which were sun dried before consumption.”
